Dockerfile -＞ Docker image -＞ Docker container

1. Dockfile -> Docker image

docker build -t shuai_image -f xxx/xxx/Dockerfile . (.不能少)

出现：
[+] Building xxx(10/17)
=> [internal] load build definition from Dockerfile
=> => transferring dockerfile:
…
=> => transferring context
=> CACHED
…


要等很久。。。。。。

2. 导入镜像

sudo docker load --input xxx/xxx/shuai_image.tar

65543534fewf2: Loading layer [>] 2.56k / 2.56k
123534fewf2: Loading layer [>] 2.56k / 2.56k
65543534fewf2: Loading layer [==================>] 2.56k / 2.56k

3. 查看镜像是否导入成功

docker images -a

4. 镜像制容器

docker run -it -p 1212:221 --name shuai_docker shuai_image
